What are the risks of using 3D printers at home?
A look at the airborne emissions from 3D printers operating in indoor spaces. Testing across commercial filaments reveals how heated materials release ultrafine particles and volatile organic compounds, while laboratory cell tests examine the impact on human airway cells. When the material used is heated to take shape, it releases tiny particles and gases into the air. Even the material commonly…
3D printers in home environments pose health risks due to airborne emissions. These printers release ultrafine particles and volatile organic compounds when the material is heated to form the desired shape. Even the most basic filament, PLA, emits particles and chemical compounds. Among the common filaments, ABS releases more particles.
In laboratory tests, human airway cells exposed to emissions from these printers showed signs of cellular stress and inflammation. When it comes to liquid resin printers, the uncooked resin can cause skin reactions or asthma, and additional hazards arise during cleaning and finishing using chemical solvents.
Experts advise against placing a 3D printer in a bedroom or office, as the print time can be lengthy. Instead, a separate room or workshop with proper ventilation, such as an exhaust system that directs air outside, is recommended. Simply opening a window is not sufficient to eliminate particles and gases.
Ventilation systems with particulate filters and activated carbon filters can help capture some pollutants, but they do not guarantee safety in poorly ventilated spaces. Moreover, printers should never be placed near flammable materials, and a fire detection system should be installed in the workspace.
